Should I try this new diet? Should I try that new one? Maybe the cabbage diet, or some other new fad that I'll drop pounds with but after the diet's over it will all come right back. IT IS NOT ABOUT A SINGLE DIET. It is about changing a lifestyle and creating new habits that promote health. Ms. Powter said it all: Gotta eat (the right stuff), gotta breathe, gotta move (that would be exercise).
